American Water lays out a plan for replacing lead pipes in its Indiana systems

Tom Neltner, J.D.is Chemicals Policy Director

The Indiana subsidiary of American Water Company filed a plan in January 2018 with the Indiana Utility Regulatory Commission (IURC) to fully replace lead service lines (LSLs) in the communities it serves within the next 10 to 24 years. The company estimates that 50,000 of its 300,000 customers in the state have lead pipe in a portion of the service line connecting the main under the street with the building.

The plan is the first submitted to the IURC in response to legislation enacted by the Indiana General Assembly in April 2017 and authored by Rep. Heath VanNatter. If the IURC approves the plan, the company can seek Commission approval to include LSL replacement on private property as an eligible infrastructure improvement whose costs can be covered by rates paid by customers.

With the plan, American Water is essentially embracing the goal articulated by EPA’s National Drinking Water Advisory Council and the American Water Works Association that the United States needs to eliminate LSLs. We applaud that goal and American Water’s commitment – while it will take time to achieve, people should not be drinking water through lead pipes, even with optimal corrosion control. Read More »

Wisconsin law removes crucial barrier to lead pipe replacement

Tom Neltner, J.D.Chemicals Policy Director and Sam Lovell, Project Specialist

Yesterday, Wisconsin Governor Scott Walker signed legislation that takes an important step to replacing the 240,000 lead service lines (LSLs) in communities across the state. SB-48 allows municipalities and water utilities to provide financial assistance to property owners to replace LSLs on private property. We described the legislation in an earlier blog – and applauded the critical work of state advocates in building support for the law.

Overwhelming local support for EPA Chemical Assessment Program: Communities impacted by PFC contamination urge Congress to maintain critical program

Samantha Lovell is a Project Specialist.

Today, a letter signed by more than 100 people was submitted to the House and Senate Appropriations Committees urging Congress to protect the EPA Integrated Risk Information System (IRIS) program. The signatories come from dozens of communities across the country impacted by PFC contamination in drinking water. EPA’s IRIS program develops critical assessments of chemicals, like PFCs, that support a wide variety of decision-making from clean-up levels at contaminated sites to setting standards that ensure clean drinking water.

As we have blogged about previously, IRIS is a non-regulatory program within EPA’s science arm that produces top-tier chemical hazard assessments used across EPA program and regional offices, other federal agencies, and state and local governments to protect public health. IRIS scientists are also called on during emergency and other rapid response situations, when technical expertise is paramount and time is of the essence.

EDF submits comments on Oregon’s proposed rules for lead testing in child care centers

Lindsay McCormick, Project Manager and Tom Neltner, J.D.Chemicals Policy Director

EDF recently submitted comments to the Oregon Department of Education’s Early Learning Division regarding the state’s proposed rules for lead testing for water in licensed and regulated child care centers.

Children are particularly vulnerable to lead exposure: even very low blood lead levels can impair normal brain development, contribute to learning and behavioral problems and lower IQs.

While national attention on lead in drinking water has spurred action to address lead in schools, fewer states have addressed lead in water in child care settings – even though these centers serve children at their most vulnerable ages.

The growing crisis over PFCs: A clear example of the need for EPA’s IRIS Program

Jennifer McPartland, Ph.D., is a Senior Scientist with the Health Program.

As I blogged about earlier, the FY2018 Interior, Environment and Related Agencies bill posted in November by the Senate Appropriations committee majority would eliminate EPA’s Integrated Risk Information System (IRIS) program. Located within the research arm of EPA, this non-regulatory program produces top-tier chemical hazard assessments used not only by multiple regulatory offices within EPA, but also by other federal agencies, regions, and states. IRIS chemical assessments, and the scientists that develop them, are relied on to support a broad range of core environmental decisions from setting clean-up levels at contaminated sites to evaluating health risks of chemicals in commerce and setting standards to ensure clean air and drinking water.

The widespread contamination of drinking water with perfluorinated compounds (PFCs)—chemicals that stick around in the environment for years and years—is a timely example of just how critical scientists within IRIS and related EPA research programs are. Across the country, governments are grappling with how to manage contamination from well-known toxic PFCs, like PFOA and PFOS, while simultaneously trying to understand potential health risks from a plethora of other less well-studied PFCs like GenX.

So what’s the job of EPA IRIS in a situation like this? Read More »

Children’s lead exposure: Relative contributions of various sources

Tom Neltner, J.D.is Chemicals Policy Director and Dr. Ananya Roy is Health Scientist

Last week, we noted in our blog that the Environmental Protection Agency (EPA) dropped the statement that paint, dust and soil are the most common sources of lead in its “Protect Your Family from Lead in Your Home” booklet. Property owners provide this booklet to prospective homebuyers and tenants in housing built before 1978. The change implicitly recognizes that there is no safe level of lead in the children’s blood, and we must reduce all sources of lead exposure. It also acknowledges that the relative contribution of air, water, food, soil, dust, and paint to children’s blood lead levels is complicated. Exposure varies significantly based on age of the home, the child’s race and age, the family’s income-level, and region of the country. Any simplification obscures these important differences.

EPA’s scientists made this clear in a model published earlier this year that pulled together the available data, divided children into three age categories, and assigned children in each category into ten groups based on their overall lead exposure. For each group, they estimated the relative contribution of air, water, food, and soil/dust (from paint). Not surprisingly, children living in older homes with lead-based paint hazards by far have the most exposure to lead. For 1 to 6 year olds in the top 90-100 percentile, more than 70% of the lead in their blood is from soil and dust. The contribution from food is 20% and drinking water is 10%. For infants, soil and dust contributes to 50% of the lead in blood, while 40% is from water and 10% from food.

Since there is no known safe level of lead in blood, we must do even more to reduce children's exposure to lead-contaminated soil and dust.

However, to prioritize action at a national level, it is important to understand how different sources contribute to lead exposure in the average child as well as the most-exposed child. We used the underlying EPA data to calculate the average relative source contribution of different sources to blood lead levels for infants from birth to six months old, for toddlers 1 to 2 years old, and young children from 1 to 6 years old. The results indicate that infants have a much higher source contribution of lead from water in comparison to older children (Figure 1). For the average child 1 to 6 years old, food is the largest source of lead exposure, with 50%, followed by soil/dust then water.
